Reduce vertical spacing between bookmark folders


I have my bookmarks arranged in folders which are in a menu off a “Bookmark” entry on the bookmarks toolbar. There is a lot of vertical space between each entry on the menu, which means (particularly on my laptop) that they don’t all fit on the screen. Is there any way to spacing between each folder name on the menu?
How can this issue be reproduced?
As above.

Expected result:
